.357 SIG is what I carry. And no, they will not stop producing it any time soon given how many LEOs carry it these days.
It's what I carry - best all around semi-auto cartridge out there these days imho, with the possible exception of 10mm. (357 SIG and 40 S&W are both off-shoots of 10mm).
What you think about, you do ... what you do, you become.
